Cold water does not boil faster than hot water, but hot water can freeze more quickly than cool water.

Why do chefs boil cold water?

Some cooks specify cold tap water because they fear the introduction of off flavors in the hot water heater and/or loss of dissolved gases yielding a “flat” flavor. This is the reason that many coffee instructions call for cold water.

Why do people boil cold water not hot water?

The rate of heating of a liquid depends on the magnitude of the temperature difference between the liquid and its surroundings (the flame on the stove, for instance). … Because it takes cold water some time to reach the temperature of hot water, cold water clearly takes longer to boil than hot water does.

What is the most efficient way to boil water?

An electric teakettle is about 80 percent efficient, although again this varies from kettle to kettle. Electric kettles are generally very well insulated, and the heating coils sit directly in the water, so less heat is lost to the air. An induction stove or hot plate is about 85 percent efficient.

Is it safe to drink boiled tap water?

How does boiling make my tap water safe? Boiling the water kills microorganisms such as bacteria, viruses, or protozoans that can cause disease. Boiling makes the tap water microbiologically safe.

Is drinking boiled water bad for you?

How Does Boiling Water Make It Safe to Drink? Boiling water makes it safe to drink in the event of some type of biological contamination.

Does salted water boil faster?

When salt is added, it makes it harder for the water molecules to escape from the pot and enter the gas phase, which happens when water boils, Giddings said. This gives salt water a higher boiling point, she said. … “The temperature of saltwater will get hotter faster than that of pure water,” Giddings said.

Does hot water actually freeze faster than cold water?

Hot water freezes faster than cold, known as the Mpemba effect. … The Mpemba effect occurs when two bodies of water with different temperatures are exposed to the same subzero surroundings and the hotter water freezes first.

How do kettles boil water so fast?

So the answer to how an electric kettle works so quickly is by using a relatively large electric current. The amount of heat produced is proportional to the current squared, so bigger currents produce much more heat—and heat things much more quickly—than smaller ones.
